Shanghai Qinkai Industry Co., Ltd. Yapa Maverengero Ekutsigira Kwepasi Pose eSt. Lucia Halls of Justice Project

CASTRIES, St. Lucia & SHANGHAI, China — Mukusimudzira kukuru kwezvivakwa zveCaribbean nekuchengetedzwa kwevanhu, Shanghai Qinkai Industry Co., Ltd., kambani inotungamira pasi rose mukugadzira uye mugadziri wekutarisira tambo dzemaindasitiri uye masisitimu ekutsigira kudengenyeka kwenyika, yakabudirira kupa Mushumo weKutsigira Dare reMagetsi neKuverengera wepurojekiti ine mukurumbira yeSt. Lucia Halls of Justice (HOJ). Inotsanangura mainjiniya emakanika akaomarara, kuverenga mutoro, uye kusimbiswa kwekuchengetedzwa kwezvivakwa kwakaitwa kumasisitimu ekutsigira kudengenyeka kwenyika akamiswa mukati menzvimbo yepamutemo inozivikanwa. Chitupa ichi chekuvaka chinomiririra danho rakakosha, kuve nechokwadi chekuti zvivakwa zvakakosha zvekugovera magetsi zveSt. Lucia's primary justice firm zvinogona kumira zviitiko zvekudengenyeka kwenyika uye kuchengetedza kushanda kwacho panguva dzenjodzi.

Basa Rakakosha reSeismic Engineering muZvivakwa zveVeruzhinji

Zvivako zveveruzhinji nemasangano emazuva ano zvinoda zvinopfuura runako chete uye hunhu hwakakosha; zvinoda simba repamusoro rekudzivirira kudengenyeka kwenyika. Izvi zvinonyanya kuitika kune zvivakwa zvematare, zvekutonga, uye zvekukurumidzira zvakaita seSt. Lucia Halls of Justice, izvo zvinoshanda senzvimbo dzakakosha dzepfungwa dzehurumende yemuno. Munzvimbo dzinonyanya kukanganiswa nezviitiko zvepasi, kuchengetedzwa kwezvinhu zvisiri zvekuvaka—zvakadai sematireyi emagetsi mashoma uye ane simba guru, mapaipi emvura, uye masisitimu eHVAC—ndiyo basa guru rekuchengetedza.

Munguva yekudengenyeka kwenyika, magetsi asina kusungirirwa zvakanaka kana kuti asina kurongwa zvakanaka anogona kutenderera zvine simba, zvichikonzera kukuvara kwechivako, kuchekwa kwemagetsi, uye njodzi huru kune vanogara muchivako. Masisitimu ekutsigira kudengenyeka kwenyika akasungirirwa anoshanda sezvibatiso zvakasimba zvinodzora kufamba kwemativi uye kwenguva refu, zvichigovera mitoro inoshanduka zvakachengeteka kudzokera muchivako chikuru chekongiri.

Kuti zvizadzise mitemo iyi yekuchengetedza, Shanghai Qinkai Industry Co., Ltd. yakashandisa musanganiswa wemitemo yekuvaka yepasi rose neyenyika. Zvivako zvekugadzira zveinjiniya zvechirongwa cheHOJ zvinosanganisira:

• GB50017-2003: Kodhi yeKugadzira Zvivako zveSimbi
• GB50009-2001: Kodhi yeKugadzira Mutoro weZvivako
• JGJ145-2013: Kodhi yeUnyanzvi yeKusimbisa Zvivako zveKonkriti Mushure meKubatanidzwa
• GB50303-2002: Kodhi yekugamuchirwa kweHunhu hwekuvaka hwemapurojekiti einjiniya yemagetsi ekuvaka
• 03S402 & 03SR417-2: Zvitsigiro zveMapaipi Emukati uye Maitiro Ekuisa

Makodhi aya anotonga kusarudzwa kwezvinhu, miganhu yekumanikidzwa inobvumirwa, zvinhu zvekuchengetedza, uye miganho yekutsauka kwemasisitimu akamiswa, zvichiita kuti bracket yega yega igadziridzwe nemuganhu wekuchengetedza wakakura.

Magadzirirwo ehunyanzvi uye dhizaini yeBracket Assembly

Iyosisitimu yekutsigira kudengenyeka kwenyikaYakagadzirirwa St. Lucia Halls of Justice inoshandisa multi-tier suspended bracket configuration (ZJ-13 Bracket) kuronga nekutsigira mhando dzakasiyana dzematireyi emagetsi. Dhizaini iyi inomiririra manetwork ekugovera ane voltage shoma neakakwira anomhanya akatarisana padenga renzvimbo iyi.

Matanho ekutakura tireyi yetambo

Kuverenga kwacho kwakavakirwa pamatanho anotevera ekutakura zvinhu zviri mumutsetse pasi penzvimbo yakajairwa yekutsigira ye 1.5 metres:

1. Matireyi eTambo Ane Voltage Yakaderera:
   • 100×100 mm (12 kg/m)
   • 200×100 mm (22.5 kg/m)
   • 300×50 mm (20 kg/m)
   • 300×100 mm (40 kg/m)
2. Matireyi Etambo Ane Voltage Yakakwira:
   • 100×100 mm (16 kg/m)
   • 200×100 mm (32 kg/m)
   • 300×50 mm (30 kg/m)
   • 300×100 mm (55 kg/m)
   • 400×150 mm (85 kg/m)

Chinhu chekuchengetedza che1.2 chinoshandiswa pamitoro yese yekutakura zvinhu kuti chiverengere kusiyana kuripo uye kuwedzera kwetambo mune ramangwana.

Kugadziriswa kweMusangano weZvivako

Muchina wekutanga unoshandisa 41×41 mm U-slot (strut channel) yakagadzirwa nesimbi yemhando yepamusoro yeQ235 carbon structural steel, yakasungirirwa neM10 screw rods uye ma anchor bolts akaiswa mu concrete ceiling slab.

Pazasi pane mufananidzo wakadzama wekugadzira unoratidza saizi chaiyo, nzvimbo, uye hardware yekubatanidza inoshandiswa muZJ-13 Suspended Seismic Support:

Sezvakaratidzwa paMufananidzo 1, chimiro chesuspension chine matanho matatu e41×41 mm U-slots ine divi re600 mm uye nzvimbo yekumisikidza ye550 mm. Kudonha kwakamira kwakabatana zvakachengeteka pamusoro pekongiri uchishandisa M10×80 concrete anchor bolts uye M10 screw rod adapters. Structural rods dzeM10 dzakasimba dzinobatanidza matanda akawanda, ayo akavharirwa panzvimbo neM10 hexagonal nuts uye M11 flat fittings, zvichipa keji yakasimba, inodzivirira kudedera.

Kunaka Kwezvinhu: Profile yeStrut Channel ye41×41 mm

Mutsipa wesimba reQinkaisisitimu yekutsigira kudengenyeka kwenyikandiyo 41×41 mm U-slot profile. Shanghai Qinkai Industry Co., Ltd. inogadzira nzira idzi dze strut kubva kuQ235 carbon structural steel, chinhu chakajairika muindasitiri chinorumbidzwa nekukwanisa kwayo kusimba, ductility, uye weldability.
